@option options [required, Aws::CredentialProvider] :credentials Your AWS credentials.

Constructor Details

#initialize(*args) ⇒ `AsyncClient`

@option options [required, Aws::CredentialProvider] :credentials

  Your AWS credentials. This can be an instance of any one of the
  following classes:

  * `Aws::Credentials` - Used for configuring static, non-refreshing
    credentials.

  * `Aws::SharedCredentials` - Used for loading static credentials from a
    shared file, such as `~/.aws/config`.

  * `Aws::AssumeRoleCredentials` - Used when you need to assume a role.

  * `Aws::AssumeRoleWebIdentityCredentials` - Used when you need to
    assume a role after providing credentials via the web.

  * `Aws::SSOCredentials` - Used for loading credentials from AWS SSO using an
    access token generated from `aws login`.

  * `Aws::ProcessCredentials` - Used for loading credentials from a
    process that outputs to stdout.

  * `Aws::InstanceProfileCredentials` - Used for loading credentials
    from an EC2 IMDS on an EC2 instance.

  * `Aws::ECSCredentials` - Used for loading credentials from
    instances running in ECS.

  * `Aws::CognitoIdentityCredentials` - Used for loading credentials
    from the Cognito Identity service.

  When `:credentials` are not configured directly, the following
  locations will be searched for credentials:

  * `Aws.config[:credentials]`
  * The `:access_key_id`, `:secret_access_key`, `:session_token`, and
    `:account_id` options.
  * ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY'],
    ENV['AWS_SESSION_TOKEN'], and ENV['AWS_ACCOUNT_ID']
  * `~/.aws/credentials`
  * `~/.aws/config`
  * EC2/ECS IMDS instance profile - When used by default, the timeouts
    are very aggressive. Construct and pass an instance of
    `Aws::InstanceProfileCredentials` or `Aws::ECSCredentials` to
    enable retries and extended timeouts. Instance profile credential
    fetching can be disabled by setting ENV['AWS_EC2_METADATA_DISABLED']
    to true.

@option options [required, String] :region

  * `ENV['AWS_REGION']`
  * `ENV['AMAZON_REGION']`
  * `ENV['AWS_DEFAULT_REGION']`
  * `~/.aws/credentials`
  * `~/.aws/config`

    This includes support for retry quotas, which limit the number of
    unsuccessful retries a client can make.

  * `adaptive` - An experimental retry mode that includes all the
    functionality of `standard` mode along with automatic client side
    throttling.  This is a provisional mode that may change behavior
    in the future.

#start_call_analytics_stream_transcription(params = {}) ⇒ `Types::StartCallAnalyticsStreamTranscriptionResponse`

Starts a bidirectional HTTP/2 or WebSocket stream where audio is streamed to Amazon Transcribe and the transcription results are streamed to your application. Use this operation for [Call Analytics] transcriptions.

The following parameters are required:

‘language-code`
‘media-encoding`
‘sample-rate`

For more information on streaming with Amazon Transcribe, see [Transcribing streaming audio].

[1]: docs.aws.amazon.com/transcribe/latest/dg/call-analytics.html [2]: docs.aws.amazon.com/transcribe/latest/dg/streaming.html

Examples:

Bi-directional EventStream Operation Example


You can signal input events after the initial request is established. Events
will be sent to the stream immediately once the stream connection is
established successfully.

To signal events, you can call the #signal methods from an Aws::TranscribeStreamingService::EventStreams::AudioStream
object. You must signal events before calling #wait or #join! on the async response.

  input_stream = Aws::TranscribeStreamingService::EventStreams::AudioStream.new

  async_resp = client.start_call_analytics_stream_transcription(
    # params input
    input_event_stream_handler: input_stream) do |out_stream|

    # register callbacks for events
    out_stream.on_utterance_event_event do |event|
      event # => Aws::TranscribeStreamingService::Types::UtteranceEvent
    end
    out_stream.on_category_event_event do |event|
      event # => Aws::TranscribeStreamingService::Types::CategoryEvent
    end
    out_stream.on_bad_request_exception_event do |event|
      event # => Aws::TranscribeStreamingService::Types::BadRequestException
    end
    out_stream.on_limit_exceeded_exception_event do |event|
      event # => Aws::TranscribeStreamingService::Types::LimitExceededException
    end
    out_stream.on_internal_failure_exception_event do |event|
      event # => Aws::TranscribeStreamingService::Types::InternalFailureException
    end
    out_stream.on_conflict_exception_event do |event|
      event # => Aws::TranscribeStreamingService::Types::ConflictException
    end
    out_stream.on_service_unavailable_exception_event do |event|
      event # => Aws::TranscribeStreamingService::Types::ServiceUnavailableException
    end

  end
  # => Aws::Seahorse::Client::AsyncResponse

  # signal events
  input_stream.signal_audio_event_event( ... )
  input_stream.signal_configuration_event_event( ... )

  # make sure to signal :end_stream at the end
  input_stream.signal_end_stream

  # wait until stream is closed before finalizing the sync response
  resp = async_resp.wait
  # Or close the stream and finalize sync response immediately
  # resp = async_resp.join!

You can also provide an Aws::TranscribeStreamingService::EventStreams::CallAnalyticsTranscriptResultStream object to register callbacks
before initializing the request instead of processing from the request block.

  output_stream = Aws::TranscribeStreamingService::EventStreams::CallAnalyticsTranscriptResultStream.new
  # register callbacks for output events
  output_stream.on_utterance_event_event do |event|
    event # => Aws::TranscribeStreamingService::Types::UtteranceEvent
  end
  output_stream.on_category_event_event do |event|
    event # => Aws::TranscribeStreamingService::Types::CategoryEvent
  end
  output_stream.on_bad_request_exception_event do |event|
    event # => Aws::TranscribeStreamingService::Types::BadRequestException
  end
  output_stream.on_limit_exceeded_exception_event do |event|
    event # => Aws::TranscribeStreamingService::Types::LimitExceededException
  end
  output_stream.on_internal_failure_exception_event do |event|
    event # => Aws::TranscribeStreamingService::Types::InternalFailureException
  end
  output_stream.on_conflict_exception_event do |event|
    event # => Aws::TranscribeStreamingService::Types::ConflictException
  end
  output_stream.on_service_unavailable_exception_event do |event|
    event # => Aws::TranscribeStreamingService::Types::ServiceUnavailableException
  end
  output_stream.on_error_event do |event|
    # catch unmodeled error event in the stream
    raise event
    # => Aws::Errors::EventError
    # event.event_type => :error
    # event.error_code => String
    # event.error_message => String
  end

  async_resp = client.start_call_analytics_stream_transcription (
    # params input
    input_event_stream_handler: input_stream
    output_event_stream_handler: output_stream
  )

  resp = async_resp.join!

You can also iterate through events after the response is complete.

Events are available at resp.call_analytics_transcript_result_stream # => Enumerator

[1]: docs.aws.amazon.com/transcribe/latest/dg/vocabulary-filtering.html
:vocabulary_filter_method (String) —

Specify how you want your vocabulary filter applied to your transcript.

To replace words with ‘***`, choose `mask`.

To delete words, choose ‘remove`.

To flag words without changing them, choose ‘tag`.
:language_model_name (String) —

Specify the name of the custom language model that you want to use when processing your transcription. Note that language model names are case sensitive.

The language of the specified language model must match the language code you specify in your transcription request. If the languages don’t match, the custom language model isn’t applied. There are no errors or warnings associated with a language mismatch.

For more information, see [Custom language models].

[1]: docs.aws.amazon.com/transcribe/latest/dg/custom-language-models.html
:enable_partial_results_stabilization (Boolean) —

Enables partial result stabilization for your transcription. Partial result stabilization can reduce latency in your output, but may impact accuracy. For more information, see [Partial-result stabilization].

[1]: docs.aws.amazon.com/transcribe/latest/dg/streaming.html#streaming-partial-result-stabilization
:partial_results_stability (String) —

Specify the level of stability to use when you enable partial results stabilization (‘EnablePartialResultsStabilization`).

Low stability provides the highest accuracy. High stability transcribes faster, but with slightly lower accuracy.

For more information, see [Partial-result stabilization].

[1]: docs.aws.amazon.com/transcribe/latest/dg/streaming.html#streaming-partial-result-stabilization
:content_identification_type (String) —

Labels all personally identifiable information (PII) identified in your transcript.

Content identification is performed at the segment level; PII specified in ‘PiiEntityTypes` is flagged upon complete transcription of an audio segment. If you don’t include ‘PiiEntityTypes` in your request, all PII is identified.

You can’t set ‘ContentIdentificationType` and `ContentRedactionType` in the same request. If you set both, your request returns a `BadRequestException`.

For more information, see [Redacting or identifying personally identifiable information].

[1]: docs.aws.amazon.com/transcribe/latest/dg/pii-redaction.html
:content_redaction_type (String) —

Redacts all personally identifiable information (PII) identified in your transcript.

Content redaction is performed at the segment level; PII specified in ‘PiiEntityTypes` is redacted upon complete transcription of an audio segment. If you don’t include ‘PiiEntityTypes` in your request, all PII is redacted.

You can’t set ‘ContentRedactionType` and `ContentIdentificationType` in the same request. If you set both, your request returns a `BadRequestException`.

For more information, see [Redacting or identifying personally identifiable information].

[1]: docs.aws.amazon.com/transcribe/latest/dg/pii-redaction.html
:pii_entity_types (String) —

Specify which types of personally identifiable information (PII) you want to redact in your transcript. You can include as many types as you’d like, or you can select ‘ALL`.

Values must be comma-separated and can include: ‘ADDRESS`, `BANK_ACCOUNT_NUMBER`, `BANK_ROUTING`, `CREDIT_DEBIT_CVV`, `CREDIT_DEBIT_EXPIRY`, `CREDIT_DEBIT_NUMBER`, `EMAIL`, `NAME`, `PHONE`, `PIN`, `SSN`, or `ALL`.

Note that if you include ‘PiiEntityTypes` in your request, you must also include `ContentIdentificationType` or `ContentRedactionType`.

If you include ‘ContentRedactionType` or `ContentIdentificationType` in your request, but do not include `PiiEntityTypes`, all PII is redacted or identified.

#start_medical_scribe_stream(params = {}) ⇒ `Types::StartMedicalScribeStreamResponse`

Starts a bidirectional HTTP/2 stream, where audio is streamed to Amazon Web Services HealthScribe and the transcription results are streamed to your application.

When you start a stream, you first specify the stream configuration in a ‘MedicalScribeConfigurationEvent`. This event includes channel definitions, encryption settings, and post-stream analytics settings, such as the output configuration for aggregated transcript and clinical note generation. These are additional streaming session configurations beyond those provided in your initial start request headers. Whether you are starting a new session or resuming an existing session, your first event must be a `MedicalScribeConfigurationEvent`.

After you send a ‘MedicalScribeConfigurationEvent`, you start `AudioEvents` and Amazon Web Services HealthScribe responds with real-time transcription results. When you are finished, to start processing the results with the post-stream analytics, send a `MedicalScribeSessionControlEvent` with a `Type` of `END_OF_SESSION` and Amazon Web Services HealthScribe starts the analytics.

You can pause or resume streaming. To pause streaming, complete the input stream without sending the ‘MedicalScribeSessionControlEvent`. To resume streaming, call the `StartMedicalScribeStream` and specify the same SessionId you used to start the stream.

The following parameters are required:

‘language-code`
‘media-encoding`
‘media-sample-rate-hertz`

For more information on streaming with Amazon Web Services HealthScribe, see [Amazon Web Services HealthScribe].

Examples:

Bi-directional EventStream Operation Example


You can signal input events after the initial request is established. Events
will be sent to the stream immediately once the stream connection is
established successfully.

To signal events, you can call the #signal methods from an Aws::TranscribeStreamingService::EventStreams::MedicalScribeInputStream
object. You must signal events before calling #wait or #join! on the async response.

  input_stream = Aws::TranscribeStreamingService::EventStreams::MedicalScribeInputStream.new

  async_resp = client.start_medical_scribe_stream(
    # params input
    input_event_stream_handler: input_stream) do |out_stream|

    # register callbacks for events
    out_stream.on_transcript_event_event do |event|
      event # => Aws::TranscribeStreamingService::Types::TranscriptEvent
    end
    out_stream.on_bad_request_exception_event do |event|
      event # => Aws::TranscribeStreamingService::Types::BadRequestException
    end
    out_stream.on_limit_exceeded_exception_event do |event|
      event # => Aws::TranscribeStreamingService::Types::LimitExceededException
    end
    out_stream.on_internal_failure_exception_event do |event|
      event # => Aws::TranscribeStreamingService::Types::InternalFailureException
    end
    out_stream.on_conflict_exception_event do |event|

    end
    out_stream.on_service_unavailable_exception_event do |event|
      event # => Aws::TranscribeStreamingService::Types::ServiceUnavailableException
    end

  end
  # => Aws::Seahorse::Client::AsyncResponse

  # signal events
  input_stream.signal_audio_event_event( ... )
  input_stream.signal_session_control_event_event( ... )
  input_stream.signal_configuration_event_event( ... )

  # make sure to signal :end_stream at the end
  input_stream.signal_end_stream

  # wait until stream is closed before finalizing the sync response
  resp = async_resp.wait
  # Or close the stream and finalize sync response immediately
  # resp = async_resp.join!

You can also provide an Aws::TranscribeStreamingService::EventStreams::MedicalScribeResultStream object to register callbacks
before initializing the request instead of processing from the request block.

  output_stream = Aws::TranscribeStreamingService::EventStreams::MedicalScribeResultStream.new
  # register callbacks for output events
  output_stream.on_transcript_event_event do |event|
    event # => Aws::TranscribeStreamingService::Types::TranscriptEvent
  end
  output_stream.on_bad_request_exception_event do |event|
    event # => Aws::TranscribeStreamingService::Types::BadRequestException
  end
  output_stream.on_limit_exceeded_exception_event do |event|
    event # => Aws::TranscribeStreamingService::Types::LimitExceededException
  end
  output_stream.on_internal_failure_exception_event do |event|
    event # => Aws::TranscribeStreamingService::Types::InternalFailureException
  end
  output_stream.on_conflict_exception_event do |event|
    event # => Aws::TranscribeStreamingService::Types::ConflictException
  end
  output_stream.on_service_unavailable_exception_event do |event|
    event # => Aws::TranscribeStreamingService::Types::ServiceUnavailableException
  end
  output_stream.on_error_event do |event|
    # catch unmodeled error event in the stream
    raise event
    # => Aws::Errors::EventError
    # event.event_type => :error
    # event.error_code => String
    # event.error_message => String
  end

  async_resp = client.start_medical_scribe_stream (
    # params input
    input_event_stream_handler: input_stream
    output_event_stream_handler: output_stream
  )

  resp = async_resp.join!

You can also iterate through events after the response is complete.

Parameters:

params (Hash) (defaults to: {}) —

({})

Options Hash (params):

:language_code (required, String) —

Specify the language code that represents the language spoken in your audio.

Amazon Transcribe Medical only supports US English (‘en-US`).
:media_sample_rate_hertz (required, Integer) —

The sample rate of the input audio (in hertz). Amazon Transcribe Medical supports a range from 16,000 Hz to 48,000 Hz. Note that the sample rate you specify must match that of your audio.
:media_encoding (required, String) —
Specify the encoding used for the input audio. Supported formats are:
- FLAC
- OPUS-encoded audio in an Ogg container
- PCM (only signed 16-bit little-endian audio formats, which does not include WAV)
For more information, see [Media formats].

[1]: docs.aws.amazon.com/transcribe/latest/dg/how-input.html#how-input-audio
:vocabulary_name (String) —

Specify the name of the custom vocabulary that you want to use when processing your transcription. Note that vocabulary names are case sensitive.
:specialty (required, String) —

Specify the medical specialty contained in your audio.
:type (required, String) —

Specify the type of input audio. For example, choose ‘DICTATION` for a provider dictating patient notes and `CONVERSATION` for a dialogue between a patient and a medical professional.
:show_speaker_label (Boolean) —

Enables speaker partitioning (diarization) in your transcription output. Speaker partitioning labels the speech from individual speakers in your media file.

For more information, see [Partitioning speakers (diarization)].

[1]: docs.aws.amazon.com/transcribe/latest/dg/diarization.html
:session_id (String) —

Specify a name for your transcription session. If you don’t include this parameter in your request, Amazon Transcribe Medical generates an ID and returns it in the response.
:enable_channel_identification (Boolean) —

Enables channel identification in multi-channel audio.

Channel identification transcribes the audio on each channel independently, then appends the output for each channel into one transcript.

If you have multi-channel audio and do not enable channel identification, your audio is transcribed in a continuous manner and your transcript is not separated by channel.

If you include ‘EnableChannelIdentification` in your request, you must also include `NumberOfChannels`.

For more information, see [Transcribing multi-channel audio].

[1]: docs.aws.amazon.com/transcribe/latest/dg/channel-id.html
:number_of_channels (Integer) —

Specify the number of channels in your audio stream. This value must be ‘2`, as only two channels are supported. If your audio doesn’t contain multiple channels, do not include this parameter in your request.

If you include ‘NumberOfChannels` in your request, you must also include `EnableChannelIdentification`.
:content_identification_type (String) —

Labels all personal health information (PHI) identified in your transcript.

Content identification is performed at the segment level; PHI is flagged upon complete transcription of an audio segment.

For more information, see [Identifying personal health information (PHI) in a transcription].

#start_stream_transcription(params = {}) ⇒ `Types::StartStreamTranscriptionResponse`

Starts a bidirectional HTTP/2 or WebSocket stream where audio is streamed to Amazon Transcribe and the transcription results are streamed to your application.

The following parameters are required:

‘language-code` or `identify-language` or `identify-multiple-language`
‘media-encoding`
‘sample-rate`

For more information on streaming with Amazon Transcribe, see [Transcribing streaming audio].

[1]: docs.aws.amazon.com/transcribe/latest/dg/streaming.html

Examples:

Bi-directional EventStream Operation Example


You can signal input events after the initial request is established. Events
will be sent to the stream immediately once the stream connection is
established successfully.

To signal events, you can call the #signal methods from an Aws::TranscribeStreamingService::EventStreams::AudioStream
object. You must signal events before calling #wait or #join! on the async response.

  input_stream = Aws::TranscribeStreamingService::EventStreams::AudioStream.new

  async_resp = client.start_stream_transcription(
    # params input
    input_event_stream_handler: input_stream) do |out_stream|

    # register callbacks for events
    out_stream.on_transcript_event_event do |event|
      event # => Aws::TranscribeStreamingService::Types::TranscriptEvent
    end
    out_stream.on_bad_request_exception_event do |event|
      event # => Aws::TranscribeStreamingService::Types::BadRequestException
    end
    out_stream.on_limit_exceeded_exception_event do |event|
      event # => Aws::TranscribeStreamingService::Types::LimitExceededException
    end
    out_stream.on_internal_failure_exception_event do |event|
      event # => Aws::TranscribeStreamingService::Types::InternalFailureException
    end
    out_stream.on_conflict_exception_event do |event|
      event # => Aws::TranscribeStreamingService::Types::ConflictException
    end
    out_stream.on_service_unavailable_exception_event do |event|
      event # => Aws::TranscribeStreamingService::Types::ServiceUnavailableException
    end

  end
  # => Aws::Seahorse::Client::AsyncResponse

  # signal events
  input_stream.signal_audio_event_event( ... )
  input_stream.signal_configuration_event_event( ... )

  # make sure to signal :end_stream at the end
  input_stream.signal_end_stream

  # wait until stream is closed before finalizing the sync response
  resp = async_resp.wait
  # Or close the stream and finalize sync response immediately
  # resp = async_resp.join!

You can also provide an Aws::TranscribeStreamingService::EventStreams::TranscriptResultStream object to register callbacks
before initializing the request instead of processing from the request block.

  output_stream = Aws::TranscribeStreamingService::EventStreams::TranscriptResultStream.new
  # register callbacks for output events
  output_stream.on_transcript_event_event do |event|
    event # => Aws::TranscribeStreamingService::Types::TranscriptEvent
  end
  output_stream.on_bad_request_exception_event do |event|
    event # => Aws::TranscribeStreamingService::Types::BadRequestException
  end
  output_stream.on_limit_exceeded_exception_event do |event|
    event # => Aws::TranscribeStreamingService::Types::LimitExceededException
  end
  output_stream.on_internal_failure_exception_event do |event|
    event # => Aws::TranscribeStreamingService::Types::InternalFailureException
  end
  output_stream.on_conflict_exception_event do |event|
    event # => Aws::TranscribeStreamingService::Types::ConflictException
  end
  output_stream.on_service_unavailable_exception_event do |event|
    event # => Aws::TranscribeStreamingService::Types::ServiceUnavailableException
  end
  output_stream.on_error_event do |event|
    # catch unmodeled error event in the stream
    raise event
    # => Aws::Errors::EventError
    # event.event_type => :error
    # event.error_code => String
    # event.error_message => String
  end

  async_resp = client.start_stream_transcription (
    # params input
    input_event_stream_handler: input_stream
    output_event_stream_handler: output_stream
  )

  resp = async_resp.join!

You can also iterate through events after the response is complete.

Parameters:

params (Hash) (defaults to: {}) —

({})

Options Hash (params):

:language_code (String) —

Specify the language code that represents the language spoken in your audio.

If you’re unsure of the language spoken in your audio, consider using ‘IdentifyLanguage` to enable automatic language identification.

For a list of languages supported with Amazon Transcribe streaming, refer to the [Supported languages] table.

[1]: docs.aws.amazon.com/transcribe/latest/dg/supported-languages.html
:media_sample_rate_hertz (required, Integer) —

The sample rate of the input audio (in hertz). Low-quality audio, such as telephone audio, is typically around 8,000 Hz. High-quality audio typically ranges from 16,000 Hz to 48,000 Hz. Note that the sample rate you specify must match that of your audio.
:media_encoding (required, String) —
Specify the encoding of your input audio. Supported formats are:
- FLAC
- OPUS-encoded audio in an Ogg container
- PCM (only signed 16-bit little-endian audio formats, which does not include WAV)
For more information, see [Media formats].

[1]: docs.aws.amazon.com/transcribe/latest/dg/how-input.html#how-input-audio
:vocabulary_name (String) —

Specify the name of the custom vocabulary that you want to use when processing your transcription. Note that vocabulary names are case sensitive.

If the language of the specified custom vocabulary doesn’t match the language identified in your media, the custom vocabulary is not applied to your transcription.

This parameter is not intended for use with the ‘IdentifyLanguage` parameter. If you’re including ‘IdentifyLanguage` in your request and want to use one or more custom vocabularies with your transcription, use the `VocabularyNames` parameter instead.

For more information, see [Custom vocabularies].

[1]: docs.aws.amazon.com/transcribe/latest/dg/custom-vocabulary.html
:session_id (String) —

Specify a name for your transcription session. If you don’t include this parameter in your request, Amazon Transcribe generates an ID and returns it in the response.
:vocabulary_filter_name (String) —

Specify the name of the custom vocabulary filter that you want to use when processing your transcription. Note that vocabulary filter names are case sensitive.

If the language of the specified custom vocabulary filter doesn’t match the language identified in your media, the vocabulary filter is not applied to your transcription.

This parameter is not intended for use with the ‘IdentifyLanguage` parameter. If you’re including ‘IdentifyLanguage` in your request and want to use one or more vocabulary filters with your transcription, use the `VocabularyFilterNames` parameter instead.

For more information, see [Using vocabulary filtering with unwanted words].

[1]: docs.aws.amazon.com/transcribe/latest/dg/vocabulary-filtering.html
:vocabulary_filter_method (String) —

Specify how you want your vocabulary filter applied to your transcript.

To replace words with ‘***`, choose `mask`.

To delete words, choose ‘remove`.

To flag words without changing them, choose ‘tag`.
:show_speaker_label (Boolean) —

Enables speaker partitioning (diarization) in your transcription output. Speaker partitioning labels the speech from individual speakers in your media file.

For more information, see [Partitioning speakers (diarization)].

[1]: docs.aws.amazon.com/transcribe/latest/dg/diarization.html
:enable_channel_identification (Boolean) —

Enables channel identification in multi-channel audio.

Channel identification transcribes the audio on each channel independently, then appends the output for each channel into one transcript.

If you have multi-channel audio and do not enable channel identification, your audio is transcribed in a continuous manner and your transcript is not separated by channel.

If you include ‘EnableChannelIdentification` in your request, you must also include `NumberOfChannels`.

For more information, see [Transcribing multi-channel audio].

[1]: docs.aws.amazon.com/transcribe/latest/dg/channel-id.html
:number_of_channels (Integer) —

Specify the number of channels in your audio stream. This value must be ‘2`, as only two channels are supported. If your audio doesn’t contain multiple channels, do not include this parameter in your request.

If you include ‘NumberOfChannels` in your request, you must also include `EnableChannelIdentification`.
:enable_partial_results_stabilization (Boolean) —

Enables partial result stabilization for your transcription. Partial result stabilization can reduce latency in your output, but may impact accuracy. For more information, see [Partial-result stabilization].

[1]: docs.aws.amazon.com/transcribe/latest/dg/streaming.html#streaming-partial-result-stabilization
:partial_results_stability (String) —

Specify the level of stability to use when you enable partial results stabilization (‘EnablePartialResultsStabilization`).

Low stability provides the highest accuracy. High stability transcribes faster, but with slightly lower accuracy.

For more information, see [Partial-result stabilization].

[1]: docs.aws.amazon.com/transcribe/latest/dg/streaming.html#streaming-partial-result-stabilization
:content_identification_type (String) —

Labels all personally identifiable information (PII) identified in your transcript.

Content identification is performed at the segment level; PII specified in ‘PiiEntityTypes` is flagged upon complete transcription of an audio segment. If you don’t include ‘PiiEntityTypes` in your request, all PII is identified.

You can’t set ‘ContentIdentificationType` and `ContentRedactionType` in the same request. If you set both, your request returns a `BadRequestException`.

For more information, see [Redacting or identifying personally identifiable information].

[1]: docs.aws.amazon.com/transcribe/latest/dg/pii-redaction.html
:content_redaction_type (String) —

Redacts all personally identifiable information (PII) identified in your transcript.

Content redaction is performed at the segment level; PII specified in ‘PiiEntityTypes` is redacted upon complete transcription of an audio segment. If you don’t include ‘PiiEntityTypes` in your request, all PII is redacted.

You can’t set ‘ContentRedactionType` and `ContentIdentificationType` in the same request. If you set both, your request returns a `BadRequestException`.

For more information, see [Redacting or identifying personally identifiable information].

[1]: docs.aws.amazon.com/transcribe/latest/dg/pii-redaction.html
:pii_entity_types (String) —

Specify which types of personally identifiable information (PII) you want to redact in your transcript. You can include as many types as you’d like, or you can select ‘ALL`.

Values must be comma-separated and can include: ‘ADDRESS`, `BANK_ACCOUNT_NUMBER`, `BANK_ROUTING`, `CREDIT_DEBIT_CVV`, `CREDIT_DEBIT_EXPIRY`, `CREDIT_DEBIT_NUMBER`, `EMAIL`, `NAME`, `PHONE`, `PIN`, `SSN`, or `ALL`.

Note that if you include ‘PiiEntityTypes` in your request, you must also include `ContentIdentificationType` or `ContentRedactionType`.

If you include ‘ContentRedactionType` or `ContentIdentificationType` in your request, but do not include `PiiEntityTypes`, all PII is redacted or identified.
:language_model_name (String) —

Specify the name of the custom language model that you want to use when processing your transcription. Note that language model names are case sensitive.

The language of the specified language model must match the language code you specify in your transcription request. If the languages don’t match, the custom language model isn’t applied. There are no errors or warnings associated with a language mismatch.

For more information, see [Custom language models].

[1]: docs.aws.amazon.com/transcribe/latest/dg/custom-language-models.html
:identify_language (Boolean) —

Enables automatic language identification for your transcription.

If you include ‘IdentifyLanguage`, you must include a list of language codes, using `LanguageOptions`, that you think may be present in your audio stream.

You can also include a preferred language using ‘PreferredLanguage`. Adding a preferred language can help Amazon Transcribe identify the language faster than if you omit this parameter.

If you have multi-channel audio that contains different languages on each channel, and you’ve enabled channel identification, automatic language identification identifies the dominant language on each audio channel.

Note that you must include either ‘LanguageCode` or `IdentifyLanguage` or `IdentifyMultipleLanguages` in your request. If you include more than one of these parameters, your transcription job fails.

Streaming language identification can’t be combined with custom language models or redaction.
:language_options (String) —

Specify two or more language codes that represent the languages you think may be present in your media; including more than five is not recommended.

Including language options can improve the accuracy of language identification.

If you include ‘LanguageOptions` in your request, you must also include `IdentifyLanguage` or `IdentifyMultipleLanguages`.

For a list of languages supported with Amazon Transcribe streaming, refer to the [Supported languages] table.

You can only include one language dialect per language per stream. For example, you cannot include ‘en-US` and `en-AU` in the same request.

[1]: docs.aws.amazon.com/transcribe/latest/dg/supported-languages.html
:preferred_language (String) —

Specify a preferred language from the subset of languages codes you specified in ‘LanguageOptions`.

You can only use this parameter if you’ve included ‘IdentifyLanguage` and `LanguageOptions` in your request.
:identify_multiple_languages (Boolean) —

Enables automatic multi-language identification in your transcription job request. Use this parameter if your stream contains more than one language. If your stream contains only one language, use IdentifyLanguage instead.

If you include ‘IdentifyMultipleLanguages`, you must include a list of language codes, using `LanguageOptions`, that you think may be present in your stream.

If you want to apply a custom vocabulary or a custom vocabulary filter to your automatic multiple language identification request, include ‘VocabularyNames` or `VocabularyFilterNames`.

Note that you must include one of ‘LanguageCode`, `IdentifyLanguage`, or `IdentifyMultipleLanguages` in your request. If you include more than one of these parameters, your transcription job fails.
:vocabulary_names (String) —

Specify the names of the custom vocabularies that you want to use when processing your transcription. Note that vocabulary names are case sensitive.

If none of the languages of the specified custom vocabularies match the language identified in your media, your job fails.

This parameter is only intended for use with the ‘IdentifyLanguage` parameter. If you’re not including ‘IdentifyLanguage` in your request and want to use a custom vocabulary with your transcription, use the `VocabularyName` parameter instead.

For more information, see [Custom vocabularies].

[1]: docs.aws.amazon.com/transcribe/latest/dg/custom-vocabulary.html
:vocabulary_filter_names (String) —

Specify the names of the custom vocabulary filters that you want to use when processing your transcription. Note that vocabulary filter names are case sensitive.

If none of the languages of the specified custom vocabulary filters match the language identified in your media, your job fails.

This parameter is only intended for use with the ‘IdentifyLanguage` parameter. If you’re not including ‘IdentifyLanguage` in your request and want to use a custom vocabulary filter with your transcription, use the `VocabularyFilterName` parameter instead.

For more information, see [Using vocabulary filtering with unwanted words].
